Abstract: FIELD: dermatology. 
     SUBSTANCE: invention can be used to treat patients with non-segmental vitiligo with a concomitant diagnosis of acne. To do this, a photosensitizer is applied to the lesions of the skin, followed by lesions exposure to the narrow-band ultraviolet radiation with a wavelength of 311 nm 2-3 times a week in the amount of 20 procedures. At the same time, prior to treatment of vitiligo, pretreatment of acne with tablets of amoxicillin + clavulanic acid at a dosage of 875 mg + 125 mg, lasting 10 days in combination with oral administration of isotretinoin 0.25-0.5 mg/kg of body weight is carried out.  
     EFFECT: method makes it possible to increase the therapeutic efficacy of vitiligo treatment and avoid the risk of recurrent course of vitiligo while shortening the treatment time for vitiligo patients by several months by eliminating the trigger factor, namely, pretreatment of acne.

Abstract: Изобретение относится к неразрушающему контролю и может быть использовано для создания внутренних дефектов сплошности в контрольных образцах для неразрушающего контроля из многослойных углепластиковых материалов. На электроды 2 и 3 от высоковольтного генератора 1 подается напряжение, создающее между частями 9 и 10 слоев 5.2 и 5.3, соответственно, электрическое поле с напряженностью Е. При подаче электрического напряжения от генератора 1, из-за анизотропных свойств удельной электрической проводимости слоев 5.2 и 5.3, изменение электрического потенциала произойдет только в частях 9 и 10 слоев, непосредственно контактирующих с электродами 2 и 3. Величина и длительность воздействия электрическим полем выбираются из условия пробоя диэлектрического слоя 6.2 на участке 11, приводящего к образованию в месте пробоя дефекта сплошности. Параметры создаваемого дефекта можно изменять путем регулировки частоты подаваемого напряжения и его амплитуды. Технический результат изобретения заключается в обеспечении возможности создания внутренних дефектов сплошности на заданной глубине и заданной площади. 2 ил.

Abstract: FIELD: radio engineering. 
     SUBSTANCE: invention relates to the field of radio engineering and is intended for application in radio communication systems employing a mode with pseudo-random reconfiguration of the working frequency. The effect is achieved by the fact that the entire time cycle of transmission is additionally divided into analysis, frequency vector transmission, and data transmission sub-cycles. The algorithm for pseudo-random selection of working frequencies and the parameters of the signal used therein remain unchanged in all sub-cycles, and a formed quaternary quadrature manipulation signal is used for data transmission in all sub-cycles. In the analysis sub-cycle, a sample data block is combined with the information block so that odd bits are attributed to the sample block and even bits are attributed to the information block. In the duration of the frequency vector transmission sub-cycle, the bit sequence of the frequency vector is combined with the information bits so that the odd bits are attributed to the frequency vector and the even bits are attributed to the information block and transmitted to the correspondent. 
     EFFECT: combination of technical procedures for controlling the suitability of working frequencies and information transmission of radio communication systems.

Abstract: FIELD: wood processing industry.  
     SUBSTANCE: invention relates to the chemical processing of birch wood and concerns the sulfation of xylane. Water-soluble salts of xylan sulfates are used as blood anticoagulants instead of heparin. Xylan sulfate is obtained by sulfating xylan in a melt of a mixture of sulfamic acid and urea. Xylan is introduced into the melt of a mixture of sulfamic acid and urea at a temperature of 110-125°C and kept under stirring for 0.5 hours. The resulting reaction mass is cooled, neutralized with a 4% aqueous solution of sodium hydroxide and filtered. The resulting filtrate is purified by dialysis. An aqueous solution of the sodium salt of xylan sulfate is concentrated under vacuum until the water is completely removed.  
     EFFECT: reducing the duration, increasing the environmental safety of the sulfating process by eliminating a toxic solvent.

Abstract: FIELD: mining industry. 
     SUBSTANCE: invention relates to the mining industry and can be used in the extraction of reserves of thin ore bodies with variable occurrence elements, unstable and medium stability of ore and host rocks. The method consists in mining the ore body by horizontal layers and adjacent paired cuts along the fall-rise of the ore body. At the first stage, ore is excavated in a layered entry. Entrances are fastened with anchor support. Next, blasting is carried out in the ore body of descending parallel contiguous boreholes or small-diameter boreholes. The chipped ore is temporarily left in the lower bench. At the second stage, a layer run is worked through the layer similarly to the overlying one. Then the ore is beaten off in the upper sidecut with ascending parallel contiguous boreholes or small-diameter boreholes and it is released together with the temporarily magnetized ore of the lower sidecut through the butt end. Ore from mining in layered entry and sidetracks is delivered to ore passes and sorted on screens by size class and content. 
     EFFECT: invention increases development efficiency, improves quality of broken ore, increases productivity and labor safety, reduces the cost of filling and breaking ore.
